- True
When the data arrives at the transport layer, the protocols at the layer start the process of data encapsulation. TCP is often called a "connection-oriented" protocol because it ensures the successful delivery of data to the receiving host. TCP divides the data received from the application layer into segments and attaches a header to each segment.
- True
We need to find the longest common prefix which is 0101011.
- False
Packet transmission time = Packet size / Bit rate
=1000/1000*1000
=10^(-3) seconds
=1 millisecond

2) IP and MAC addressing. True or False. One point for each correct answer, zero points for each incorrect answer. Many of the questions refer to the following network consisting of three 10Mbps Ethernet segments, one switch, and one router. Assume all ARP tables are up-to-date unless otherwise stated. a) Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses. True...
